Dave, The P0700 code is a generic fault code indicating the the TCM (transmission control module) has recognized a problem and the P0755 is the indicated problem. I'd recommend you check your transmission external electrical connector for water intrusion and corrosion at the terminals by disconnecting the connector. If nothing appears wrong, I'd then recommend you drop the lower transmission pan and take a look at the residue deposit that is laying on the bottom of the pan. You should only see a relativily minor amount of grayish, black clutch material residing there. Pay particular attention for a gross amount of this or any large particular material, including any metal, either filings or chunks, or any brass or aluminum. If this checks out to be fairly clean, then I'd recommend you replace that "B" solenoid (2-3 shift solenoid) and have the trans. pan and filter replaced.; I'd also highly recommend you have the trans flushed for anyother particular matter that may reside internally inside the transmission. You'll have to have the codes cleared and the transmission relearned for shift feel, at that point.

SOURCE: 96 dakota p1391 error
intermittent loss of ckp or cmp.problem is in the distributor.make sure rotor not loose or distributor hold down bolt loose.camsensor on the distributor.also check to see if crank sensor is loose and out of adjustment.

I recommend changing your transmission fluid to see if that helps solve the issue....
Otherwise, you may have to change the solenoid pack as the screen filter in it will clog, and stick the solenoids.

P1391 - Intermittent loss of CMP or CKP.
Generally, this code will indicate that the crankshaft sensor is faulty. The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft. I would check the wiring harness for loose connections. Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage. replace if needed.
If a crank or cam sensor fails, the engine will not start. both of these sensor circuits can be checked with a voltmeter or lab scope.If the sensors are receiving the correct amount of voltage and have good low-resistance ground circuits, their output should be a pulsing digital signal or voltmeter reading while the engine is cranking.
If any of these conditions do not exist, the circuit needs to be repaired or the sensor needs to be replaced. The location of the Cam shaft sensor will be mounted on the distributor. Use the sensors terminals for testing. Over 7 volts is ok, but anything below that at the sensor will indicate that the sensor wires are bad. If the voltage is low at the PCM, the PCM is suspect.

P0700 code is a generic code for Transmission Control System Malfunction
P1776 code means your solenoid switch valve is stuck in low reverse. (DTC 47) A stuck solenoid switch valve is a common occurrence in the valve body of the Dodge 41te transmission.
The first step would be to check the wiring to the solenoid from the TCM, then maybe try a new solenoid pack if the wiring is determined to be fine.
